Abstract
A display element includes: a base substrate; a metal layer on the base substrate; a passivation film on the base substrate and covering the metal layer; an electrode on the passivation film and at least partially overlapping the metal layer; and a pixel defining film on the passivation film. The pixel defining film has an opening at least partially exposing the electrode, and portions of the electrode offset from the metal layer are below a portion of the electrode overlapping the metal layer such that trenches are defined in the opening.
